Abstract

Complicated dynamic interactions in multi-grid-connected converter (GCC) systems have unexpected impacts on the overall response of the system. Online state sharing between different GCCs can enhance coordination of the whole system. However, due to the significant communication delay, the power angle and frequency states cannot be transmitted rapidly enough. In this letter, an innovative power angle remote estimation method is proposed to realize real-time power angle and frequency information sharing between different GCCs with local measurement of voltage and power. This method decouples interactive information by revealing the transient response mechanism of the network. The proposed method could inspire distributed cooperative control and online transient stability analysis for multi-GCC systems.
